    That Greek pilot seems to be criticising the F-104 because it didn’t have the avionics of an F-4 and the turning ability of an F-5 – does he not realise that you can’t have everything in the same airframe?

    uh….

    any one besides me feeling de javu all over again?

    heard that somewhere before… ah, right, F/A/B-111.

    You’re comparing Sixties technology with today’s – there was no such thing as relaxed stability ‘fly-by-wire’ in the F-111’s day.

    easy to maintain, and with an ideal performance conditions for Afghan women – in short, perfect aircraft for the mission, surpassing even the obvious rival North American manufacturing, the Sikorsky UH-60 Blackhawk.

    Huh!

    THe Blackhawk helicopters in use in Afghanistan could be up to 30 years old with thousands of hours on their airframes – how many 30 year old Mi-8s are there in the world?:rolleyes:

    I’ve seen it written somewere, that the F-16 has better endurance, range than an F-15. The F-16 carries less fuel but burns at exactly half the rate, compared the F-15…

    Looks an awful lot like an F-35 in the above view – maybe that was the artist’s intention?:diablo:

    F-35 over-engineered? It might be a complicated aircraft, but it is doing the job normally given to 3 different aircraft designs, so on the whole, it’s actually simplifying things and making things more cost effective…

    How about Tu-160 as an over-engineered plane? what can it do that the simpler, cheaper Tu-95 can’t do?

    You’d wonder who actually pays for the development costs of a derivative of an airliner that has sold all of 50 or 60 examples in the last 20 years…

    e.g.
    1. USSR design philosophies meant uncomplicated or agricultural systems were required so that they could be understood by “tractor mechanics” and operated from a field in the middle of no-where.

    That’s something of a stereotype of Soviet engineering – do you regard Tu-160, MiG-31, S-300 or Akula class submarine as “agricultural engineering”?:confused:

    The boss of Ryanair, Michael O’Leary, actually expects the small regional airports of Europe to pay his airline to use their facilities and not the other way around – I dare say MOL has the same attitude to the aircraft producers, certainly Boeing have said they felt they were “raped” after doing business with Ryanair.
    I don’t think that airlines want to go back to having flight engineers and navigators and radio operators and the like, for that’s why we have so much electronics on an airliner – to reduce workload on the people flying them, and on those servicing and repairing them.

    Sorry
    ie none of them was equipped with MAWS, which basically makes AMRAAM worthless at BVR.

    Does that include all radar-guided anti-aircraft missiles – will S-400 be rendered impotent by MAWs and other EW?

    Indeed, and that was a technique used by F-105 and F-4 pilots to escape from MiGs in Vietnam – but it didn’t work all the time for the Americans, and it didn’t work all the time for the MiG-25 either…

    Some people understand that perfectly, but also know that the best tactical conditions for the VPAF were worse than anything the USAF has faced since 1942. A comparison with Korea is revealing.

    Generally that’s why countries and armies loose wars, because the’re at a disadvantage – ultimately, it would explain why the North Vietnamese essentially lost the air war at least. I wasn’t trying to say that the F-105 was a brilliant dogfighter, just trying to bring in some background to the subject.
    The subject does make me reflect upon how so few fighter aircraft were originally designed for “dogfighting”. Until the introduction of the Typhoon, I don’t think the RAF has had a fighter that was designed for close fighting since the 1950s – even the Hunter must have been designed first and foremost to shoot down bombers, that’s what the heavy gun armament was for, and the same could even be said for the MiG-15 and ’17’, with their single 37 and two 23 mm guns

    Nor was the F-4, F-105, Mirage III, or even the MiG-21. In fact, most “fighter” aircraft from the Fifties and Sixties were never intended for close-in combat – they were usually designed to shoot down bombers. The F-105 was a bomber – but it shot down 27.5 MiGs ‘guns only’ in the Vietnam war.

    For a definition of an over-engineered aircraft i guess we’ed have to say it’s any aircraft whose role or appointed mission could be replaced by a cheaper aircraft, both in purchase price, and in operational costs.

    Quite on the contrary, for me the MiG-25 is a classic example of a purposefully engineered aircraft – the exact opposite of over-engineering. Quite frankly, who else could design a M3.0 aircraft cheap and rugged enough to be operated even by countries like Algeria, Azerbaijan, Syria or Libya?

    There was nothing that those Arab countries needed in air defence that the cheaper and less complicated MiG-21 or Mirage F1 could have done instead of the MiG-25 could do.
    Foxbat – cheap? rugged? really…:rolleyes:

    Well that’s the interesting question. The F-22 could still be considered an immature type in USAF service, and only a reduced number are going to be purchased, which will increase overall life cycle costs. Basically, does the USAF get real value for money. Did the USAF get value for money and a real increase in capabilities with the SR-71 or the F-15 – answer is yes, they probably did, but no other NATO member could have afforded the either type.

    The same parallel could be made with the MiG-25 and MiG-31, only the former USSR or the present day RF could afford both types and have an actual need for them:

    I guess no aircraft or system should be considered overengineered or expensive if a country has the financial, technical resources and the need for the capability – it’s all relative.
